Who really owns your house?

If your fortunate enough to own your home, that's great! But for the millions of us that don't , we are stuck with one bank? Or are we? It has come out now that with all the foreclosures that are happening allot of people who thought they knew who the mortgage holder on their house is have no clue!! And to make it worse, the banks and other lenders have been playing hide and seek with our homes! In fact, there have been so many foreclosures that there has been fake employees signing off on many documents!
